The vertebral arches have been trimmed away to reveal the vertebral canal in the cervical region. On the right side of the specimen the pedicles of the fourth and fifth vertebrae have been cut across so that the right vertebral artery (10) is visible with three of its segmental spinal branches. The atlas has been entirely removed from the specimen.
